Abstract

The purpose of the project is to study the technical and financial feasibility of producing specific equipment for laboratories of experimental animals in this country, with a view to introducing them. To do this, it is expected to undertake two basic engineering projects, one of them using conventional technology and the other based on this technological innovation. The progress of biomedical research has demanded ever more sophisticated animal models in relation to sanitary control. Obtaining animals sanitarily compatible with the best international standards has required considerable spending on the animal houses, particularly as regards the buildings and equipment. One of the most significant points is the control of the atmosphere of the animal houses, including the control of the temperature and the relative humidity, as well as the proper removal of pollutants, such as ammonia, from the animals’ environment. The technology currently employed on this control uses expensive systems and equipment of doubtful efficiency, since most of the time, they consist of adaptations of systems or equipment standardized for use in establishing human comfort levels. Experiments are underway intended to establish specific equipment for animal houses. The preliminary results suggest encouraging results from the standpoint of sanitary standards for the animals, with the possibility of lowering both investment and maintenance costs. (AU)
